BeautifulSoup - How to Loop Through a "tr" Tag?

Question

I'm trying to loop through this BeerAdvocate page (https://www.beeradvocate.com/beer/styles/35/) in order to scrape the beer name, abv, rating and so on. However, I'm not sure how to build a loop to go over the whole page.

For example, I'm doing as follows regarding the beer name:

import requests
from bs4 import BeautifulSoup
url = "https://www.beeradvocate.com/beer/styles/35/"
results = requests.get(url) 

soup = BeautifulSoup(requests.get(url).content, 'html.parser')
beer_name = []

beer_div = soup.find_all('div',id='ba-content')

for container in beer_div:

#beer name
name = container.find_all('a')[12].text
beer_name.append(name)

print(beer_name)

Does anyone know what I'm doing wrong here?

Thank you!

First identify the table, then find all the tr tags within the table, then loop through the tr tags to print the text.

beer_table = soup.find('table')

tr_tags = beer_table.find_all('tr')[3:]

for tr in tr_tags:
    beer_name.append(tr.td.text)

beer_name = beer_name[:-1]

print(beer_name)

Output:

['Ayinger Celebrator', 'Troegenator', 'Spaten Optimator', 'Salvator', 'Korbinian', 'Samichlaus Classic Bier', 'Samuel Adams Double Bock (Imperial Series)', 'Consecrator', 'Andechser Doppelbock Dunkel', 'Birra Moretti La Rossa', 'Perkulator Coffee Dopplebock', 'EKU 28', 'Liberator Doppelbock', 'Augustiner Bräu Maximator', "Smuttynose S'muttonator (Heritage Series)", 'Butthead Doppelbock', 'Autumnal Fire', 'Weltenburger Kloster Asam-Bock', 'Wasatch The Devastator Double Bock', 'St. Victorious', 'Urbock 23°', 'Voodoovator', 'Saxonator Dunkles Doppelbock', 'Doppel-Hirsch', 'Josephs Brau Winter Brew', 'Duck-Rabbator', 'Troegenator - Bourbon Barrel-Aged', 'Ettaler Curator Dunkler Doppelbock (US Import Version)', 'Blonde Doppelbock', 'Snow Blind Doppelbock', 'Doppelbock Dunkel', 'Tucher Bajuvator Doppelbock', 'Dark Heathen Triple Bock', 'Winter Bock', 'Deep Water Dopplebock', 'Doppelbock Grande Cuvée Printemps', 'Lobotomy Bock', 'Sled Dog Dopplebock', 'Primátor Double Bock Beer', 'Icelandic Doppelbock', 'Dopple Bock', "St. Nikolaus Bock Bier - Brewer's Reserve", 'Double Skull', 'Emancipator Doppelbock', 'Winter-Bock', 'Granitbock', "Henry's Farm Double Bock", 'Double Vision Doppelbock', 'Massacre', "Fireman's Brew Brunette Beer"]

Here is the full code:

import requests
from bs4 import BeautifulSoup
url = "https://www.beeradvocate.com/beer/styles/35/"
results = requests.get(url)

soup = BeautifulSoup(results.content, 'html.parser')
beer_name = []

beer_table = soup.find('table')

tr_tags = beer_table.find_all('tr')[3:]

for tr in tr_tags:
    beer_name.append(tr.td.text)

beer_name = beer_name[:-1]

print(beer_name)

Hope that this helps!

To correctly parse the HTML, use lxml or html5lib parser:

import requests
from bs4 import BeautifulSoup

url = 'https://www.beeradvocate.com/beer/styles/35/'
soup = BeautifulSoup( requests.get(url).content, 'lxml' )

print('{:<60} {:<70} {:<10} {:<10}'.format('Name', 'Brewery', 'ABV', 'Ratings', 'Avg'))
print('-' * 150)
 
for row in soup.select('tr:has(.hr_bottom_light)'):
    tds = [td.text for td in row.select('td')]
    print('{:<60} {:<70} {:<10} {:<10}'.format(*tds))

Prints:
